If you can't play as her then you're going to do horribly. There are only two types of people that play as Poppy. The kind that can play her really well. Then there is the kind that have seen a good player and thought, "That champs OP why does no one play as her". Thats the reason why she is so unpopular because people will try her and be disappointed but if they stuck around they would do really well.
